Virus

February 22nd, 2009 in The Other Place

The prime directive of all organisms is to reproduce and survive, which is also the case for viruses, which in most cases are considered a nuisance to humans.

Viruses – An Overview

Viruses possess both living and non-living characteristics. The unique characteristic that differentiates viruses from other organisms is the fact that they require other organisms to host themselves in order to survive, hence they are deemed obligate parasites.

Viruses can be spread in the following exemplar ways

Airborne – Viruses that infect their hosts from the open air
Blood Borne – Transmission of the virus between organisms when infected blood enters an organisms circulatory system
Contamination – Caused from the consumption of materials by organisms such as water and food which have viruses within
Therefore viruses have many means of getting transmitted from one organism to another.

Cell Assimilation by a Virus

Viruses are tiny micro-organisms, and due to their size and simplicity, they are unable to replicate independently. Therefore, when a virus is situated in a host, it requires the means to reproduce before it dies out without producing more viruses.

This is done by altering the genetic make up of a cell to start coding for materials required to make more viruses. By altering the cell instructions, more viruses can be produced which in turn, can affect more cells and continue their existence as a species.

The following is a step by step guide of how an example bacteriophage (a virus that infects bacteria) takes control of its host cell and reproduces itself.

The virus approaches the bacteria and attaches itself to the cell membrane
The tail gives the virus the means to thrust its genetic information into the bacteria
Nucleotides from the host are ‘stolen’ in order for the virus to create copies of itself
The viral DNA alters the genetic coding of the host cell to create protein coats for the newly create viral DNA strands
The viral DNA enters its DNA coat
The cell is swollen with many copies of the original virus and bursts, allowing the viruses to attach themselves to other nearby cells
The process begins all over again with many more viruses attacking the hosts’ cells
Without a means of defence, the host that is under attack from the virus would soon die. The next page looks at how organisms defend themselves from these ruthless viruses.

Felt Tin

February 17th, 2009 in The Other Place

This happened twice so I know it’s true.

We were discussing my job, and saying I should quit and go to Leeds.

The Pirate pulled out an old tobacco tin covered in an intricate design made from matchsticks.

He opened it and it was full of animal silhouettes made from coloured felt.

As he pulled each one out it became thin and larger and stuck to the wall.

They started to move and make noises.

Copenhagen Interpretation

February 11th, 2009 in The Other Place

Postulates that the observer obeys different physical laws than the non-observer, which is a return to vitalism. The definition of an observer varies from one adherent to another, if present at all. The status of the wavefunction is also ambiguous. If the wavefunction is real the theory is non-local (not fatal, but unpleasant). If the wavefunction is not real then the theory supplies no model of reality.
